This example demonstrates creating a multi-color floating box chart.<br><br>
This chart is composed of 4 box-whisker layers, created using <a href="XYChart.addBoxWhiskerLayer.htm">XYChart.addBoxWhiskerLayer</a>. Each layer handles boxes of one color. Only the "box" part of the box-whisker layer is used.
